3-way mixing unit with Clip system

S9000-MIX is an electric motor actuator designed for operating rotary mixing brass valves (FMV 131C, FMV 132C, FMV 133C). Actuators are controlled by 3-point signal. S9000-MIX units can be manually operated.

Valves are available in DN 15 – DN 25, with internal or external thread or compression fittings and are rated PN10.

S9000-MIX actuators with FIRŠT FMV 131C,132C,133C valves are designed for use in radiator, floor or remote heating systems and other small and medium sized heating or cooling systems.

Three types of connections are available: internal thread (FMV 131C), external thread (FMV 132C) and compression fittings (FMV 133C).
